为了获得YAG激光(λ=1.06μm)对人眼视网膜损伤阈值(即视网膜出现50%损伤率时照射到眼睛上的激光能量)的数据,确定人眼对YAG激光的最大允许照射量,我们先对青紫蓝灰兔及恒猴作了连续及脉冲YAG激光的照射试验,用加权直线回归方法统计、计算了兔眼及猴眼的YAG激光损伤阈值,并算出了在损伤率达50%时兔眼及猴眼所需的激光能量的比例.一、实验装置、要求及方法所选用的连续和脉冲YAG激光器均要求单膜输出,输出的能量变化率控制在5%以下.光路安
In order to obtain the data of YAG laser (λ = 1.06μm) on the human retinal damage threshold (ie, the energy of the laser beam striking the eye when the retina is damaged by 50%) and to determine the maximum allowable irradiation of YAG laser by the human eye, we first The continuous and pulsed YAG laser irradiation experiment was conducted on the blue-purple blue rabbit and the monkeys, and the damage threshold of YAG laser in rabbit eye and monkey eye was calculated by weighted linear regression method. Eye and monkey eye laser energy ratio required First, the experimental device, requirements and methods selected continuous and pulsed YAG lasers are required single-film output, the output rate of change of energy control less than 5%
